SUSANVILLE — A lone gray wolf that has zigzagged hundreds of miles through Oregon and California has been moving east and is now in Lassen County.

California wildlife officials said Tuesday that the male wolf, the first gray seen in the state in more than 80 years, moved from eastern Shasta County to the state”s northeastern Lassen County this week.

The 2-year-old wolf known as OR7 was fitted with a GPS tracking collar last spring.

State Fish and Game spokesman Mark Stopher tells the San Francisco Chronicle that OR7 traveled east through rugged, forested terrain in search of a new mate and territory to start his own pack.
